Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, MARCUS P. NIENDAM, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Non-Refillable Bottle, of which the following is a specification.

This invention relates to non-refillable bottles and other receptacles for liquids.

The main object of the invention is to provide a construction which will prevent the substitution of one liquid for another.

A further object is to provide a construction in which it is practicable to use glass for the various parts with which the liquid comes in contact.

Further objects are to provide a device of the character described in which the mechanism operates with ease, which is simple, and which is commercially practicable.

The accompanying drawings illustrate the invention, and referring thereto Figure 1 is a view, partly in vertical section, of the upper part of a. bottle constructed with the present invention. Fig. 2 is a similar view showing the bottle inverted. Fig. 3 is a section on line :c -:r Fig. 1. Fig. 4 is a section on line sc -m Fig. 1. Fig. 5 1s a section on line :v w Fig. 1. Fig. 6 is an inverted perspective in section on line w"'ac of Fi 4.

1 (Iesi nates the body of the bottle which is forme with a neck 2 flaring upwardly and outwardly, there being a valve seat 3 formed in the lower part of the neck upon which normally rests a float valve 4. The valve 1 is hollow, as shown, to cause it to float when about two-fifths submerged in liquid. This valve 4 is preferably made of glass but if desired, it could be formed of cork, rubber or other suitable material.

Within the neck 2 is an intermediate valve support 5 having four vertical grooves 6 and a central aperture 7 undercut or beveled as shown permitting an easy outward flow of the liquid. The support 5 has a seat 8 for a spherical sinker valve 9 which when the bottle is right side up, rests upon its seat 8 and prevents liquid from passing down through the aperture 7. The valve support 5 below the valve seat 8 has four grooves 10. The upper grooves 6 do not extend below the upper rim of thevalve seat 8 so that the valve seat has an unbroken annular concave face which closely its the valve 9.

Above the intermediate valve support is a valve retainer 11 having an upper concave face 12 and a central aperture 13, and suspended below the valve retainer 11 by pins 0. is a baflle plate 1).

Above the valve seat 3 a chamber 1 1 is formed within the neck 2; this chamber is larger than is required for the low of the liquid and forms a lower air storage space.

Formed by the neck above the valve seat 8 is a chamber 15 in which the valve 9 operates; this chamber is larger than the chamber 14 and larger than required for the flow of liquid and forms an air storage space. The chambers 14. and 15 promote the steadiness of flow of the liquid and admit air into the bottle readily as the liquid is poured out.

The passage through valve seat 3 is slightly larger than the aperture 7, while the passage 13 is the same size as passage 3. The passage 7 is smaller than the passage through valve seat 3 to prevent an intake of liquid when holding the bottle in a horizontal position and before any liquid can pass the upper valve seat 8 the bottle must be tilted enough to allow passages 7 and 13 to become level andv before such can be accom plished the valve 9 will roll into its seat by gravity and prevent any passage of liquid.

Should an attempt be made to siphon the liquid when the bottle is inverted, the valve 4 will float upward as the liquid enters the chamber 14 and the valve will be carried into its seati3 and thus prevent passage 01' the liquid.

The baffle plate b and upper edges of valve support 5 prevent the possibility of introducing wires or instruments into the neck to interfere with the regular operation of the ball valves.

In construction, after filling the bottle with the liquid it is to contain the valve 4 is dropped into its seat. The valve support 5 is next put in place and if desired may be cemented. Then the valve 9 is dropped in 100 place, and the baflie plate I) and valve re- 1 and valve retainer for supporting the baffle tainer 11, both of which have been previously assembled as shown in Fig. 6, and cemented together, are then placed in the neck and cemented in place.

hat I claim is 1. In a non-refillable bottle, a flaring neck in the lower part of which is a valve seat, a spherical float valve for said seat, a valve retainer in said neck, said retainer having a central aperture, an intermediate valve support with a central aperture smaller than the opening through the valve retainer, said valve support having a valve seat and vertical grooves above and below said seat, a s herical valve for the latter seat, a baflie p ate under the aperture of the valve retainer, and pins connecting the baffle plate plate.

2. In a non-refillable bottle, a neck, means forming upper and lower air chambers a valve in the upper chamber normally closing communication between the two chambers, a valve in the lower chamber normally closing communication between the lower chamber and the body of the bottle, the upper valve passage being smaller than the lower valve passage.

In testimony whereof, I have hereunto set 30 my hand at Los Angeles California this 26th day of May 1906.
